ABSTRACT Pulmonary lymphangitic carcinomatosis refers to the tumor spread into the lymphatic system of the lungs and is considered a poor prognostic marker. We present an interesting case of adenocarcinoma of right lung evaluated with 18F-FDG PET/CT for baseline staging, with extensive bilateral lung involvement and lymphangitic carcinomatosis pattern. Subsequently, the patient received 3 cycles of carboplatin- and pemetrexed-based chemotherapy regimen along with oral ceritinib. Complete metabolic response and significant reduction in size of the primary lung lesion was noted on response evaluation with 18F-FDG PET/CT, which is a rare phenomenon.
